A Guide to Technology

There are many viewers of LCD television faces problem of ghosting, means pictures shadow seems to be left of the main picture i.e. unwanted image on the screen, appearing superimposed on the desired image. Maximum viewers are facing this problem when they connected their PC to the large (example 32 inches and above) LCD TV.

There are many reasons behind this issue:
1. Cable quality issue.
2. Length of the cable.
3. VGA compatibility.
4. Mismatched impedance along the communication channel.
5. Multi path distortion.

Solution:

Firstly, user is aware to buy good quality connecting cable and if the length between PC and LCD is so far it creates attenuation problem. So, the desired signal is loss and then it shows ghosting problem. Generally, VGA is not compatible with large LCD because it can not generate proper signals as required. So, use graphic cards having DVI interface or HDMI out put that supply High quality signals that’s resolves ghosting problem.

For Television channels recommends only DTH services for Good reception quality.
If set-top box having facility of multiple output like HDMI, Component video and AV out then first preference is for HDMI out, second preference for Component video and third for AV out.

If connecting media (transmission cable) is effected from external interface (electromagnetic and magnetic distortion) that is caused by Speakers, wires, ups etc. So, you can take these things away from your connecting media.
